The God:
That's right.
You can't pick up a lump of momentum and carry it around with you. Nor can you pick up a lump of charge. You can pick up things that have momentum or charge, but those things don't exist as substances in and of themselves. And energy is the same. You can't pick up a lump of energy. Energy isn't a substance. Neither is momentum or charge.
Ok, you stand in front of a high speed bullet or touch a highly charged capacitor with other hand on earth. Then may be you will understand that momentum or charge is not accounting system.
Did anyone tell you that they are substance? I think I told you that they are not accounting system.
